Application filed October 15, 1921.

To all whom it may concern Be it known that we, HARRY D. MOSAUER andLEON LAUB, citizens of the United States, residing at New York, in thecity,

5 county, and State of New York, and Newark, in the county of Essex andState of New Jersey, respectively, have invented certain new and usefulImprovements in Dice;

and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The objects of this invention are to provide a pair of dice which may behandled and played as a unit; to provide in such a unity means forobtaining the usual combination of numbers which may be obtained by useof two separate dice; to provide an article which will always rest withthe dice face exposed upwardly; to make the dice roll straight when castor thrown; to secure simplicity of construction, ease-of manipulationand neatness of appearance, and to obtain other advantages and resultsas may be brought out in the following description.

Referring tothe accompanying drawing, in which like numbers of referenceindicate similar parts throughout the-several views;

Figure 1. is a side elevation of the dice embodied in our invention; A

Figure 2 is a longitudinal central section through the same, and

Figure 3 is an end view of the dice.

In the specific embodiment of the inven tion illustrated in saiddrawing, the refer-- ence numerals 1, 1 indicate disc like rotarymembers the edge or circumference of which is shown as flattened off asa hexagon. These rotary members are arranged so as to stand up upon edgeand expose one of the flattened faces upwardly. These flattened facesmay have any suitable markings upon them such as the usual dots 2ordinarily used upon dice. By providing six of these faces, the dotswill number one to six on the several faces as is usual in dice. Each ofthe rotary members 1 has a central hole 3 through which any suitablepivot or trunnion 4 may be inserted for the'said member to rotate upon.This pivot 4 is shown in the present instance as comprising pinsinserted toward each other in the two rotary members and having theirends secure in a connector 5. The pins have heads at their outer endsSerial No. 507,972.

for preventing the rotary members from sliding off and the connector 5is large enough to prevent the rotary members from moving toward eachother. The complete device therefore resembles in some respects adumb-bell, and as the rotary members are separated far enough inproportion to their diameter, the device when cast or thrown will cometo rest with bothrotary members upon the surface in an upright position.Consequently they will both show some number on the top just as a pairof individual dice when cast will show numbers. virtue of the rotatablemounting of both of the members which are upon the pivot 4, anycombination of numbers from one to six may be obtained, and furthermorethe dice when cast will have a tendencyto roll along straight since thesame isbalanced and both members are freely rotatable.

Obviously other means of mounting the v rotary members may be employed,the essential feature being that both of the members are rotatable andprevented from coming together or coming off. Furthermore, the rotarymembers may have more or less than six flattened surfaces in accordancewith the desires of the manufacturer, and other detail changes andmodifications may be made in the construction and use of our improveddice without departing from the spirit or scope of the invention, and wedo not wish to be understood as limiting ourselves except as set forthin the following claim when construed in the'light of the prior art.-

, Having thus described our invention, we

claim In a device of the character described, the

combination of a pair of independently rotatable dice members havingrelatively short.

axes compared to their diameters, a con-v nector having ends adjacentthe said dice members, said ends having relatively short and means onsaid connector rotatably supporting said dice members through said.

axes.

In testimony whereof we affix our signatures.
